To all whom t may concern Be it known that I, GEORGE A. ARNOLD, a citizen of the United States of America, re-

siding in the borough of Manhattan, city,-

a suitable motor, means including disks car-` rying tappets for operating the puncturing devices in order and proper sequence in accordance with telegraphic transmissions corresponding to the characters or letters on the key-levers. Each ofthe disks is controlled by a character lever of the keyboard and connected to the shaft4 so as to make a full revolution each time its key lever i`s depressed. The strip feeding device also receives motion from the continuously `rotating shaft through the medium of a set of gears and a clutch controlled by cams on the tappet disks in such manner as to cause the feed device to act during the time the puncturing devices are operated by the sets of tappets on each disk. A tension take-up is provided to relieve strain on the strip while the punches are in operation.

In the accompanying drawings: Figure 1 is a'plan view of the machine with the frame partly broken away: Fig. 2, a front elevation with the key-board removed, showing some of the parts in section: Fig. 3, a left-hand side elevation, with the feed conneet-ing gear eliminated: Fig. 4, a transverse sectional view on an enlarged scale,

taken on the line 4, 4, Fig. 1: Fig. 5, an

enlarged plan view of some of the tappetdisks, feeding mechanism, etc., at the left hand side of the machine: Figs. 6 and 7 are detached views of parts shown in Fig. 5: Fig. 8 illustrates a part of one of the keylevers and adjustable spring connections: Figs. 9 and 10 are sidey elevations of two of the tappet carrying disks: Fig. 11 isa derocked as hereafter described.

`'The puncturi'ng apparatus is located inA tached view of the strip tension take-up dev ice: and Fi 12, a detached view of a frictlon clamp or holding the strip before .it reaches the puncturing devices.

The key board a, comprises key leversb tted to rock on a transversely arranged shaft 0 and a yspacing bar ,d similar to the corresponding parts found in ordinary typewriters. Each key lever is provided with a tension spring e adjustably connected to the frame of the machine through, the medium of an angle plate f, a screwy and clamping bar h. Arran ed in bearings in the frame parallel to sha c are three shafts j and In. The shaft i is continuously rotated by a power transmission gear Z adapted to be connected to a suitable motor which may be placed on a bracket m on the frame. The other shafts y' and la are provided with downwardly projecting arms n, and o, respectively, equal in number to the keylevers of the key-board, and normally held in the positions shown in Fig. 4 by springs. One such spring acting on shaft j is shown at p, Fig. l, the other spring acting on the shaft 7c being beneath the spring p and partly hidden thereby. At or near the central parts of the shafts j and k are located notched wheels g and r fitted to rotate on the shafts, and fast on the shafts adjacent these notched wheels are levers s and t carrying pawls u, o, arranged to act on and move the notched wheels g and r one notch each time their respective shafts j and 7c are front o wheels g and r and embraces two punches. fw and upheld by springs acting etween collars on the punches, and by a guide bar y that forms a guide for the lower ends of the unches, their upper ends being uided in the upper part z of the punch rame, the lower part of which carries die plate 1. The punches are offset transversely relatively to the strip of paper 2, which is moved between the ends of the punches and the die plate by a feeding device that uniformly moves the strip when the machine is operating. As the punches are actuated alternately, as hereafter described, some of the pairs of perforations in the groups telegraphically representing'the letters or characters on the linger pieces ofthe key-boardY are arranged in transverse lines at right angles to the longitudinal line of the strip,

Fig. (1. Other arrangements of the punctures or perforations in the stri may be eifected by variations in the positions and operation of the punches, but those shown and here described produce a transmitting strip suitable for use in the Delany systemof telegraphy now used commercially by thev TelepostCompany.

To operate the punches fw, there are n, provided levers 3 and 4 fulerumed at 5 and 6 on a bracket frame extending upwardly from the main frame of the machine and whose forward ends act on the tops of the and 10 are suitably set relatively to the notched wheels g and 1*. l

Fitted to rotate freely on the hubs4 of ratchet wheels 13, keyed rigidly to shaft i, are tappet carrying disks 14, one for each of the key levers b. The inner end 15 of each key lever lies along one side of its disk which is held in inoperative position by a pin 1 6 thereon that abuts against the end of the controlling lever. 4This lever holds the v spring acting pawl 17, pivoted on the side of the disk, outI of engagement with the ratchet wheel 13, Fig. 4. Each disk 14 is provided with two sets of tappets 19 and 20 secured toits sides, extending beyond its periphery and arranged to act on the arms n and o of the shafts g and 7', respectively,`

when the disk is caused vto be rotated upon the depression ofthe keyboard end of the lever b, which causes the' 'end 15 to release the 'pawlf 17 and disengage .th'e pin 16, whereupon the pawl is immediately enga ed by the rotating ratchet wheel and the dis is caused to rotate therewith and as the ltappets strike and pass by the arms n and o the shafts j and 7c are rocked, their pawls u and v respectively moving the notched wheels g andr and so actuate the punches w and as before described. ANow when the disk has been carried around by the shaft z one full .revolution the linclined end 18 of pawl 17 and stoppin 16 comein contact with the end 15 of the controlling key-lever, it having been relieved'of pressure on its key-board end, thereby moving the awl 17 away from the ratchet wheel 13 and arresting further motionof `the disk until said key-lever is 4again manipulated. During such revolution of the disk all ofthe tappets have acted on the arms of the rock shafts and `caused as many punctures to be' made in the strip ot' paper as there are tappets. The arran ement and number of tappets on the disk etermine the arrangement of the punctures in the group and as the depression of the different key-levers should produce different groups of punctures, the number and positions of the tappets on the disks will correspond to the groups of punctures to be produced. Two such disks detached from the machine are shown at Figs. 9 and 10.

To operate the strip feeding device which consists of a pair of rollers 21, 22- geared together and held in ya suitable frame or housing 23, each disk is provided with a cam 24 whose active surface is different on the diii'erent disks toaccord with the lengths of the strip required to be fed for each group of punctures so'as to avoid unnecessary waste Vof the strip and secure proper spacing of the groups of punctures, see Figs. 4, 9, and 10. To impart motion to the feed rollers from thecams 24, a bar 25 pivoted at 26 to the main frame is provided with projecting plates 27 acting as wipers one for each of the cams 24. This bar is under the influence of a strong spring 28 that acts to hold the wipers against the cams. These wiper plates 27 are seated in slots formed in the upper edge of t-he bar 25 and are held therein by a cap plate or bar 25 secured by screws to the bar 25 and having a tongue or a e on its under side which fits into a longitu inal groove in the bar 25 and into notches formed in t-he upperedges of the wipers, see Fig. 6; which figure also shows how the bar'4 25, as it rocks on its pivot 26, acts on a sliding rod 29 through an arm 30 projecting therefrom and embraced between lugs projecting downwardly from the bar 25. The rod 29 slides in bearings on the end of the main frame and has at its forward end an upwardly extending arm 31 against which rests an arm of a bell crank lever 32 rocking on a stud bearing 33. The other arm of this bell crank is forked so as to engage a groove in a sliding part 34 of a clutch'splined to a. short shaft 35 extending through the end of the main frame, and there provided with a gear 36 connected through an idler gear 38 with a gear wheel 37 secured to the end of the continuously rot-atingshaft z'. The co-actin part of clutch 39 rotates in a'bearing 40 an 4is secured to a miter wheel 41 whose fellow wheel 42 is attached to the lower end of a vertical shaft 43, 'the rupper end vof which is, by a pair of miter wheels '44, placed in communication with the feed roller 21, of the feeding device. By this arrangement it is seen that the shaft 35 rotates with the mainshaft z', normally without imparting motion to the feed rollers, and that when the sliding rod 30 is moved by the rockin bar 25, arm 31 releases bell crank lever 32 andl allows'the The winding up shaft is-driven by a belt 53 runningA over a slip friction pulle on the shaft 50- and a pulley on the sha of one 'bars or rollers 5 over the other the strip passes, (Fig. 11)

The strip 2 to be punctured is carried on a reel 46 and passes under a. roller on an arm 47 to a friction clamp 48,- thence to the puncturing device'and feeding device after passing through a tension take-up 49, and from the feedingdevice to the winding up shaft 50 carried on an 'adjustable arm 51 lhaving a clamp connection 52 to the main frame.

of the feed rollers.l The spring 28 is sulficiently strong to overcome the reaction of spring 45. The function of the friction clamp 48 is that of a brake to prevent an overrun of thepaper that would cause slackness at the leading side of the puncturing device. To make such a brake delicate in its adjustment and insure uniformity of pressure onthe whole width ofthe strip the frontend of the upper plate 54 is. extended inwardly from a spring plate which overlies it and whose rear end restson a projection from the under plate 55, and an adjusting screw 56 i passes through the spring into the under plate, Fig. 12.

The strip feeding device Vis acting while 'the punches are acting, and although the punches act very quickly there would be a tendency to tear the strip or distort the punctures, and to obviate thisI is the function of the` take-up device 49. This device consists of a short shaft held in a bracket bearing andcarr ing on one of its ends two under one of which and 'the `pull on and direction of movement of the strip being indicated by 'an arrow. A torsionaly spring 58 on the shaft has one of its ends -fired-to the bracket and its other end xedftoithe collar 59 which can be set in any position onV the shaft so that the tension oA the spring may be adjusted to a strength to cause the strip to be pulled through the clamp 48 and yield-to the pull ofthe feeding' device when a punch is in the strip.

The means employed for putting the feeding rollers 21, 22 into action when the spacing bar ol is manipulated, consists ofa lever 60 fitted to rock on thebar or shaft c with its forward end'beneath the frame of the spacing bar which .is pivoted to the main frame at 61, 61. .The inner-end of this lever is in line with the inner ends of the finger leilers ,5 and is adapted to act as a stop for lthe stop pin onl the disk 62 and to control when released as the spacing bar is manipulated. rI`he operation is similar to the action of the other disks and their controlling levers. This disk 62 is provided with a cam, similar in character to the other cams 24 lon the other disks 14, that acts on a wiper at the e'nd of the rocking bar 25, and so closes` communication between the feed rollers and the shaft j through the clutch 34, 39, as before described.
